This paper examines strict Nash networks in the noncooperative directed flow model of Bala and Goyal (Econometrica 68(5):1181–1230, 2000) with partner heterogeneity (payoff of a player in a link depends on the identity of her link partner). We focus on the asymmetries with regard to the...

We study the formation of mutual insurance networks in a model where every agent who obtains more resources gives a fixed amount of resources to all agents who have obtained less resources. The low resource agent must be directly linked to the high resource agent to receive this transfer. We...

In this paper we characterize efficient networks for network formation games with global spillovers, that satisfy convexity and sub-modularity properties. This allows us to complete the work of Goyal and Joshi (2006) and Westbrock on collaborative oligopoly networks. In particular, we establish...

Our paper belongs to the strand of literature associated with the notion of Nash networks introduced by Bala and Goyal [1] in the connections model. Our aim is to consider situations where agent i has concerns about the validity of information that she acquires from agent j. Independently...

We provide existence results in a game with local spillovers where the payoff function satisfies both convexity and the strategic substitutes property. We show that there always exists a stable pairwise network in this game, and provide a condition which ensures the existence of pairwise...

In this article, we examine the role played by heterogeneity in the popular “connections model” of Jackson and Wolinsky (J Econ Theory 71(1):355–365, <CitationRef CitationID="CR5">1996</CitationRef>). We prove that when heterogeneity with respect to the values of resources, or the information decay parameter, depends on the identity...</citationref>

In this paper, we pursue the line of research initiated by Haller and Sarangi (2005). We examine the existence of equilibrium networks called Nash networks in the non-cooperative two-way flow model by Bala and Goyal (2000a,b) in the presence of partner heterogeneity. First, we show through an...

This paper addresses the existence of Nash equilibria in one-way flow or directed network models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path connecting them. We find that heterogeneity in...

This paper addresses the existence of Nash networks for the one-way flow model of Bala and Goyal (2000) in a number of different settings. First, we provide conditions for he existence of Nash networks in models where costs and values of links are heterogenous and players obtain resources from...
